Thus, mixotrophy can enable these bacteria to dominate in mixed populations when both chemolithotrophic and chemoorganotrophic nutrients are present (Gottschal et al., 1979; Kelly and Kuenen, 1984). The litho is a word with a Greek root meaning stone, thus this group of bacteria is called stone eaters (2). [1] These molecules can be organic ( chemoorganotrophs) or inorganic ( chemolithotrophs ).
